This symposium was held 1-5 November at Keio University Hiyoshi Campus. It was the first step in development of a major research project which aims to advance urban design theory related to dialectical couple density/intensity by: (a) focusing on dialectical relationship between concrete (multiple) densities and (multiple) intensities; (b) emphasizing and addressing the complexity arising from recognition of cultural specificity of the urban; defining local assessment criteria (as measure of responsibility and responsiveness of design proposals). The spatial focus of the project is on two types of urban environment which commonly understood as extreme poles of intensity: busy public transport hubs and ordinary residential areas,with their corresponding, high and low densities and diversities. Special emphasis is on possibility of representation(s) and quantifications of key qualitative aspects of the urban. The project explores spatial and temporal nodes of urban intensification and their dialectical interrelationship, intensities associated with places, rhythms and the resultant socio-cultural uniqueness. While aiming to be comprehensive in its scope, special attention of the project will be given to detection, definition, recording, representation and, eventually, "measuring" of those intensities which are considered to be non-measurable, such as human encounter, mnemonic aspects of space/place etc. The project focuses on the examples from Tokyo and selected Asian cities (Bangkok, Beijing, Hong Kong, Singapore). Those will be investigated and benchmarked against referential cases from Europe (Barcelona, Belgrade, Copenhagen, Florence) and Australia (Melbourne).
